pintle-receiving ears of a hinge. In the arrange

and four ears ‘I at the other end. When the
blank is bent or rolled into a tubular form, each
of the ears 6 enters the space betweentwo of the
shell or the like.

The various features of novelty whereby my in
vention is characterized will hereinafter be point
ed out with particularity in the claims; but, for
a full understanding of my invention. and of its
objects and advantages, reference may be had
to the following detailed description taken in
connection with the accompanying drawing,
wherein:
-

Figure 1 is a longitudinal central section
through a faucet embodying the present inven
. tion, the faucet being shown open, and a portion
of the valve _stem or actuator being in elevation;
Fig. 2 is a section on line 2-2 of Fig. 1; Fig. 3
is a view similar to Fig. 2, showing the valve
turned sumciently to close the faucet; Fig. 4 is
40 an enlarged elevation of the sleeve valve, a lon
gitudinal section being b?oken away to expose
the inner side of the sleeve at the joint between
the meeting ends of the band or_ plate from which
the sleeve is made; Fig. 5 is a view, on a. smaller
scale than Fig. 4, showing the sheet or plate from
which the valve sleeve is made, in a iiat condi
tion; Figs. 6 and l'1 are top plan views of two of
ears 1.
Inward deflection of the metal of the '
ysleeve begins at some distance from the two sets
of ears, so as to avoid abrupt bends and cause
o
the free ends of the ears to extend inwardly well
toward the axis of the sleeve.\

I prefer, also, to cut i_nto the ends of the blank
at about the longitudinal center of the latter, 35
